Kaley Cuoco is a bride-to-be after the "Big Bang Theory" star's now-fiance, equestrian Karl Cook, revealed Thursday evening that he had popped the question on her 32nd birthday. Cook shared a video of the emotional proposal on Instagram.

Cuoco is seen with tears streaming down her face and the engagement ring on her finger as she tells the camera, "We're engaged!"

Cook captioned the unforgettable moment, "Who knew my prior post was oracular. Well after nearly two years I finally got up the courage to ask her to marry me. This is the best night of my life and I think the video shows it is the best night for kaley as well.....of she said yes!!!!!"

"On my loves birthday I got her everything she has always wanted....now judging by her face maybe not, it's the thought that counts right," he wrote on Instagram.

For the proposal, Cook planned an intimate, candlelit dinner for the pair, which was documented on Cuoco's Instagram story. It took a turn when Cook said he ran into a chandelier and was seen icing his forehead.
